My son LOVES classical music. Every time I play it for him he starts babbling and smiling while looking around. Although most of the time his eyes start to get heavy and he ends up falling asleep. I put it on for him before his naps now. He’s 8 weeks and I just started playing it for him a couple of weeks ago. Seeing how relaxed he gets makes me feel guilty for not playing it for him sooner, or in the womb like my mom used to with me and my siblings.
